The claim was specific and reassuring. At a news conference on July 21, Health and Human Services Secretary Robert F. Kennedy Jr. said, 'We do have the outbreak under control,' and said the source had been identified through extensive forensics [1].

The company at the centre of the investigation had said something different two days earlier. In a July 19 statement, Taylor Farms wrote: 'Today, we were informed that FDA made a mistake, and this was a false positive' [2]. It went further: 'To be clear, at this moment, FDA has not identified a single positive product test result for Cyclospora' [2].

The scale is not in dispute. The five-state outbreak linked to Taco Bell and Taylor Farms has produced 1,644 cases and 94 hospitalizations, with no deaths, across Michigan, Ohio, Indiana, Kentucky and West Virginia, with illness onsets from May 13 to July 13 [3]. Nationally, 2026 has produced 1,645 lab-confirmed domestically acquired cases across 34 states and 141 hospitalizations, with more than 5,100 further illnesses under review [3].

What the investigation has to work with is epidemiology rather than a laboratory match to a product [3]. That distinction is precisely what 'the source has been identified' would require.

Two days after the secretary spoke, the FDA disclosed a second cyclospora outbreak: 72 people as of Wednesday, no product identified, the location undisclosed [4]. HHS described it as 'an active investigation, and officials are working together to determine the specific cause of illnesses in this cluster' [4].
